#PARSER PQL ... |
Remark: It is important to define the right parser as Odysseus cannot determine the parser based on the query text!
Comments
Comments mark lines that should be ignored by the parser. Useful for additional information for the reader. Comments are defined by using three slashes per line. Currently, there is no way to comment multiple lines at once.

Variables can be used to reuse certain values. MostlyIn most cases, they are moved to the top of a file so that they become more clearlyvisible. A variable can be created by using #DEFINE and be removed by using #UNDEF. If a variable should be calculated out of from other variables (or constants), #EVAL can be used. To access a varibalevariable, the user has to write $ ${....}. The existence of a variable (if it is created or not) can be checked with #IFDEF. The value of a variable can be printed by using #PRINT (into the console). The following example shows three variables: an integer called "currentid" that has the value "50", a variable named "path", which has the value "F:/odysseus/example/" and a calculated variable "maxid".

Additionally, system properties provided by / environment variables provided by System.getProperty(...) and System.getPropertygetenv(...) are also available. To avoid nameing naming collisions, each system property has "_" as prefix. Example: ${_user.name} will be replaced with the current system user name (NOT the username in Odysseus).
